About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-75S
The AirTAC SAIJ80X115-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a carbon steel rod and a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The G3/8 PT ports and 25 mm rod diameter provide a robust interface for demanding pneumatic setups.
With a nominal stroke of 115 mm and a 75 mm adjustment range, this model provides a highly flexible usable travel window from 40 mm to 115 mm. Delivering a push force of 4523 N at 0.9 MPa, it is designed for applications requiring significant thrust alongside precise end-position tuning. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-75S Is Used
Variable End-Stop Positioning
Ideal for machines where the retract distance must be fine-tuned on the fly, using the 75 mm adjustment screw to set the exact end position within the 40-115 mm travel window.
Product Size Changeover
Perfect for production lines handling varying product sizes, allowing operators to quickly adjust the cylinder's effective stroke without changing out the entire actuator.
High-Force Clamping Setup
Delivers 4523 N of clamping force at 0.9 MPa while permitting precise control over the clamping depth during initial machine commissioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-75S the Right Cylinder?
Choose this 80 mm bore cylinder when you need substantial thrust—4523 N at 0.9 MPa—combined with a wide 40 to 115 mm adjustable travel window. If your application requires less force, the 63 mm bore offers 2805 N at 0.9 MPa; if you need more, the 100 mm bore provides 7068 N. The rear adjusting screw allows you to dial in the exact retract position during commissioning or product changeovers without adding external stops or swapping the cylinder.
Because the stroke is 115 mm, side-load risks are moderate, but always ensure proper external guiding for optimal seal life. Remember that the rear adjuster functions strictly as a travel stop, not a lock; the cylinder will not hold its load without live air. For load-holding requirements, consider the SAIL or BSAI series. To match this ISO 15552 interchangeable cylinder, specify: 80 mm bore, 115 mm stroke, 75 mm adjust, PT G3/8 port, CMSE/DMSE magnet, and an appropriate mounting bracket.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-75S FAQ
The rear adjuster acts as a mechanical stopper that lets you trim the effective stroke by up to 75 mm. For a nominal 115 mm stroke, this creates a usable travel window of 40 to 115 mm, allowing precise end-position tuning without external stops.
At an operating pressure of 0.9 MPa, the SAIJ80X115-75-S generates a push force of 4523 N and a pull force of 4041 N. It operates efficiently at speeds between 30 and 800 mm/s.
